[Gdb] New GDB debugging stub for DJGPP |

Recently, I tried to set up serial GDB support in our DJGPP application. I
generally run my application under Win98 - not DOS - and I pretty much
couldn't make it work with the stub included in the DJGPP distribution. It
appeared to me that characters just weren't getting transmitted/received
reliably.
So, I began casting about for serial libraries that I might use to replace
the unreliable BIOS calls. What I ended up with, ultimately, is a nice
modular method for using whichever serial library you might already have in
your application.
I've currently written function layers for SVAsync (what I used originally
for development), DZComm (what we're going to use for some other stuff in
our app), and BIOS calls (buyer beware). I found that debugging performance
was best by far with DZComm.
Since I moved to a Bit-Free Zone(tm) some months ago, my server is without
any connectivity so I have nowhere to host this file. I'm attaching it here
- it's only 11K - so that someone can put it someplace more reasonable. It
doesn't have the Makefile or the sample app so as to save space.
Hope this helps folks out!
